    RTL-SDR TCP Server on Raspberry Pi 3

Quick start:

Install current Raspbian Lite to an SD card
Place empty ssh file in /boot to enable remote access
Set hard-coded DHCP IP for RPi in Router
Install stuff (sudo apt-get update && sudo apt-get install rtl-sdr apache2 php5)
Copy rtl-sdr-server to /etc/init.d, change hard-coded IP
Make script executable (sudo chmod a+x /etc/init.d/rtl-sdr-server)
Enable script at boot (sudo update-rc.d rtl-sdr-server defaults)
Move index.php page into webroot and remove apache example index.html
Move 020-web file to /etc/sudoers.d to enable PHP script to start & stop server

Have fun :)
